The attorney for Martin's family, Benjamin Crump, says the evidence is "irrelevant" and predicted it would never be used at Zimmerman's trial.

"Is the defense trying to prove Trayvon deserved to be killed by George Zimmerman because the way he looked?" Crump said in a statement released Thursday.

"If so, this stereotypical and closed-minded thinking is the same mindset that caused George Zimmerman to get out of his car and pursue Trayvon, an unarmed kid who he didn't know. The pretrial release of these irrelevant red herrings is a desperate and pathetic attempt by the defense to pollute and sway the jury pool."

Instead, he said, jurors will focus on Zimmerman's arrest for battery on a police officer, a domestic violence injunction and other issues he said demonstrate a "propensity for violence."
